System Lifecycle Phases

Our Services using four design stage/phase which based on systems development life cycle in combine together with V-Model engineering. 

<p>Conceptual Phase</p>

Conceptual Phase

The conceptual system that fit your process engineering requirements to minimize cost in project from safety point to plant integration.
Design Phase 
Design Phase 
The design of the automation system based on the conceptual requirements. This is a cyclic development where  reassessment of system concept and automation costing happen.
Production Phase 
Production Phase 
The programming of automation systems based on design stage, critical design review, safety Review, and automation simulation. 
Commissioning Phase
Commissioning Phase
Site production, and Acceptance testing for operation and live system evaluation. This is where we do onsite installment and IO testing.

Conceptual design

The conceptual design stage is the stage where an identified need is examined, requirements for potential solutions are defined, potential solutions are evaluated and a system specification is developed. The system specification represents the technical requirements that will provide overall guidance for system design. Because this document determines all future development, the stage cannot be completed until a conceptual design review has determined that the system specification properly addresses the motivating need. 

Key steps within the conceptual design stage:

  • Need identification.
  • Feasibility analysis.
  • System requirements analysis.
  • System specification Conceptual.
  • Design review. - Services | Conceptual Phase offer
  • P&ID Piping & Instrumentation Diagram development.
  • URS - User Requirement Sheet development.
  • FDS - Functional and Design Specification development.
  • PFS - Process Flow Diagram.
  • Automation Safety Design (SIL/PL Calculation).
  • ATEX instrumentations / IS Loop Calculation. 
  • Automation System Concept.
Design Phase

Design Phase 

Preliminary system design phase 

During this stage of the system lifecycle, subsystems that perform the desired system functions are designed and specified in compliance with the system specification. Interfaces between subsystems are defined, as well as overall test and evaluation requirements. At the completion of this stage, a development specification is produced that is sufficient to perform detailed design and development. 


Key steps within the preliminary design stage include:

  • Functional analysis 
  • Requirements allocation 
  • Detailed trade-off studies 
  • Synthesis of system options 
  • Preliminary design of engineering models 
  • Development specification 
  • Preliminary design review - Services | Design Phase offer
  • Automation Confiuration Design.
  • SCADA Design.
  • Electrical Wiring Design.
  • Safety Wiring Design.
Production Phase

Production Phase 

Detail design and development

This stage includes the development of detailed designs that brings initial design work into a completed with form of specifications. This work includes the specification of interfaces between the system and its intended environment and a comprehensive evaluation of the systems logistical, maintenance and support requirements. The detail design and development is responsible for producing the product, process and material specifications and may result in substantial changes to the development specification. 


Key steps within the detail design and development stage include:

  • Production and/or construction of system components 
  • Acceptance testing 
  • System distribution and operation
  • Operational testing and evaluation
  • System assessment - Services | Production Phase offer
  • PLC Programming template development.
  • PLC Programming.
  • HMI Programming template development.
  • HMI Programming.
  • Batch Recipe development.
Commissioning Phase

Commissioning Phase

On Site Production and construction

During the production and/or construction stage the product is built or assembled in accordance with the requirements specified in the product, process and material specifications and is deployed and tested within the operational target environment. System assessments are conducted in order to correct deficiencies and adapt the system for continued improvement.


Key steps within the product construction stage include: 

  • Production and/or construction of system components.
  • Acceptance testing.
  • System distribution and operation.
  • Operational testing and evaluation.
  • System assessment. - Services | Commissioning Phase offer
  • IO Test.
  • Engineering Parameter Setup.
  • Process Automation Pressure Test.
  • Process Automation Leak Test.
  • Process Automation Water Test.
  • FAT Automation.SAT Automation.
  • Process / Machinery Simulation.
  • Process / Machinery Safety Simulation.
  • Operator Training.
  • Automation Manual Book.
